Dear Tianwei, You can use the -analyze option to the opt tool to tell the DSA passes to store their results in files. When you use the -analyze option, the DSA passes will create a separate file for each function (and possible one file to hold the globals graph). For this reason, I recommend running opt in a special empty directory because DSA will generate *a lot* of files. Second, to

Hi, all, We are working on a static analysis phase on LLVM's IR, we want to do a backforward phase through the use-def chain, I knew that LLVM had a built-in SSA form which provide the use-def chain for virtual register variables, however, I want to know if you also provide some kinds of use-def chain for memory operations? for example, I have the following source code int foo(int *q, int

Afaik gold does not help here. I tried it and managed to only generate native code. I'm currently investigating an alternative approach to produce whole-program bitcodes: 1) add

In lto+pgo some (5 out of 12 with usual suspect like perlbench and gcc among them using -flto -Wl,-mllvm,-use-cfl-aa -Wl,-mllvm,-use-cfl-aa-in-codegen) the CINT2006 benchmarks don’t compile. Has the implementation been tested with lto? If not, please stress the implementation more. Do we know reasons for gains? Where did you expect the biggest gains? Some of the losses will likely boil down to

Hello everyone, I'm working on passing parameters for gold/LTO plug-in and could add this one as well. Just need an option name. Could anybody suggest one?

On CINT2006 ARM64/ref input/lto+pgo I practically measure no performance difference for the 7 benchmarks that compile. This includes bzip2 (although different source base than in CINT2000), mcf, hmmer, sjeng, h364ref, astar, xalancbmk On Sep 15, 2014, at 11:59 AM, Hal Finkel <hfinkel at anl.gov> wrote: > ----- Original Message ----- >> From: "Gerolf Hoflehner"

Hi, all: Recently I am debugging the DSA and want to learn how it work, and now I am checking the local datastructure analysis. I use the following command to print the graph: (gdb) p g.dump() digraph DataStructures { label="Function addG"; Node0xe1f3a0 [shape=record,shape=Mrecord,label="{ i32: MRE\n|{<g0>}}"]; Node0xe1f4d0

Hi, Kelly, Have you found the solution for this problem? I met a similar problem when I were trying to test MySQL 5.0 with LLVM. The following is my step, but still failed since llvm-ld can not recognize some gcc link flags. 1. during the configuration, use a script such as llvm-gcc.sh, at this time the script only invoke the gcc. This is necessary because the gnu configure will test the
